Overview
The AD7265BSUZ, produced by Analog Devices Inc., is a high-performance, dual 12-bit successive approximation analog-to-digital converter (ADC). This component is designed for low power consumption and high throughput rates, making it suitable for a variety of applications requiring precise and efficient analog-to-digital conversion. The AD7265 operates from a single 2.7 V to 5.25 V power supply and features throughput rates of up to 1 million samples per second (MSPS). It includes two ADCs, each preceded by a 3-channel multiplexer, and a low noise, wide bandwidth track-and-hold amplifier capable of handling input frequencies in excess of 30 MHz.
